A year after the events in Dracula: Prince of Darkness (1966) Monsignor Ernest Mueller visits the village to ensure that all is well. He learns that the locals no longer attend mass, even though Dracula is dead, because the shadow of his castle touches the church and they feel that the castle still contains evil. To allay their fears, the Monsignor performs a ritual at the castle to rid it of all evil. The local village priest however accidentally reawakens the frozen Dracula who seeks his revenge on Monsignor Mueller, specifically targeting his niece Maria.
